Group,
I'm testing with PPP authen chap callin and was unable to get it to work.
I'm under the impression that with this command, the calling router will not
send a challenge to the called router. And authentication is done by the
called router. But it is not behaving that way. Is my understanding how
"callin" works incorrect?
Here's config for the calling router:
interface BRI0
no ip address
no ip directed-broadcast
encapsulation ppp
dialer pool-member 1
isdn switch-type basic-ni
isdn spid1 xxxxxxxxxxxxxx
isdn spid2 yyyyyyyyyyyyyy
ppp authentication chap callin
ppp multilink
!
interface Dialer1
ip address 152.3.65.2 255.255.255.252
no ip directed-broadcast
encapsulation ppp
dialer remote-name r5
dialer idle-timeout 45
dialer watch-disable 20
dialer string xxxxxxxxxx
dialer pool 1
dialer watch-group 1
dialer-group 1
ppp authentication chap callin
ppp multilink
Debug output:
